Study Of Adulteration Identification And Technology Of Assaying In Edible Bird's-nest And Its Preparation

It is the first time that the liquid chromatography method for the acetylneuraminic acid and aminosaccharide test of cubilose and its products has been established in this article, this method has the good versatility ,high sensibility and good accuracy, it can be used in the study of assaying and identification of acetylneuraminic acid in cubilose and its products.As the detection technique for the enterprises and quality supervision departments of the food and drug manufacturing, it has been universal in detection agencies in China because the simple instrumenttation, good specificity and relatively cheap price. The establishment of liquid chromatography method of acetylneuraminic acid test conduces to administration for the enterprises and quality supervision departments. It is significance to regulate the health care products market and to protect the consumer rights.The glycoprotein of the cubilose contains large amounts of N-acetyl-L-neuraminidase, usually known as acetylneuraminic acid, and it is the characteristics substance of the cubilose because of the a relatively fixed content in cubilose,and also as the basis of assaying of the cubilose. It requests the hydrolization of the acetylneuraminic acid and the liquid chromatography test method of cubilose and its products in this article.
